Abstract (en)

[origin: EP0435179A2] A multilayer silver halide color photographic mateial comprising a support having thereon a yellow color forming silver halide emulsion layer, a magenta color forming silver halide emulsion layer and a cyan color forming silver halide emulsion layer, wherein the cyan color forming silver halide emulsion layer contains at least one oil-soluble cyan coupler capable of coupling with an oxidation product of an aromatic primary amine developing agent to form a substantially diffusion-resistant dye, represented by formula (I), at least one member selected from the compounds represented by formulae (II) and (III), and at least one compound represented by formula (IV). The silver halide color photographic material can be rapidly processed. Fluctuations of cyan dye density obtained therefrom owing to change in compositions of processing solutions can be prevented, and deterioration of the image formed therefrom during storage, due to cyan dye density caused after color development processing, can also be prevented.
